As the bottle sank into the water, it began to glow. The scales in the bottle flowed out and began to take shape, but none of them seemed to be sticking to Joanna's legs.
Soon enough, she had a blond-haired, blue-eyed, green-tailed mermaid sitting in her lap.
The mermaid's hair reach about to her stomach. Besides the large two-feet-long three-feet-wide fan-like caudal fin at the end of her tail, there was a fin on either side of where her shins would have been, two fins on top of where her thighs would of been, a fin on either arm from her wrist to her elbow, and a fish-like (as opposed to a dolphin's or shark's) dorsal fin on her lower back.
There was also some webbing between her fingers, connecting them all at the knuckle halfway between her palms and her fingertips. Her ears looked pointed as well. She was roughly seven feet and a half feet from the top of her head to the tips of her caudal fin.
Her breasts, at least as much as Joanna could see from that angle, looked firm and were about 42D.
The mermaid's caudal fin flapped against the edge of the tub.
"Would you mind scooting back?", she blushed and smiled as she asked.
